COMBINATION HEATER Application led October 8, 1920.

To aZ whom t may concern.'

Be it known that I, PETER REINHARDT, a citizen of the United States,Vresidino at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Combination Heatersand Cookers, of which the following is a. specification.

This invention relates to gas heaters, and more particularly to thesmall portable type usually adapted to be connected with a source of gassupply such as the ordinary jet, by means of a flexible tube, not shown.

An object of my invention is to provide, in a heater of the classdescribed, improved means, whereby a portion of the heated air is causedto be intercepted and discharged at a particular position on the heater,where lsmall utensils may be so placed as to become heated by the air asit rises from the discharge openings, for the purpose of cooking food orheating water and the like.

'A further object of the invention is to provide a heater of the classdescribed, which is of simple, cheap construction, serving s1-multaneously as a heater, and cooking stove, the parts being arranged soas to effect two separate constantly active hot air discharges, when isuse.

To this end, the invention consists in the construction, combination andarrangement of parts hereinafter 'described and claimed.

In the drawings forming part of this specification,

Figure 1 is a perspective View of the invention.

Fig. 2 is a vertical 2 2 of Fig. 1, and

Fig. 3, is a horizontal sectional view on line 3-3 of Fig. 1,

A designates a rectangular box-like casing or shell formed with a flattop 1, a bottom 2, side walls 3 and 3', and a back 4. B designates acurved deileetor plate secured by means of bolts 4 to the wall 4, andextending laterally between t-he side walls and spaced above and below,a distance from said top and bottom, so as to form a hollow floor and ahollow roof effecting air spaces or chambers C and C', said chambersbeing symmetrical about a longitudinal vertical plane located central ofthe casing. The top 5 and bottom 6 of the detlector plate whichconstitues a lining for the casing, is curved toward the front of thelatter in a manner to form an arcuate floor b sectional view on lineSpecification of Letters Patent.

and ceiling C for the space within the lining which constitutes thecombustion chamber. At its front the casing is formed with an upper andlower front wall and 8 respectively, said walls joining with the walls land 2 respectivelyY and with the horizontal long edges of the lining tocorn Jletely inclose the air spaces C and C. he walls 7 and 8 are spacedvertically to form a long main hot air front outlet opening D of uniformheight extending across the front of the casing and being located nearerthe bottom to the top of the casing. Supported by the walls 3 and 3.soas to extend from one to the other, horizontally ofthe casing at aposition midway between the front and rear walls of the latter nearerthe ceiling c of the lining than to the lower edge of the wall 7 is theburner E. The burner consists of a horizontally disposed pipe 10 closedat the end supported in the wall 3, and extending through the wall 3',and having at its outer end a suitable gas valve 11 having a ribbed coneend 11', whereby the supply of gas may be cut ofi'.

Adjacently surrounding the pipe 10 and cutting through the wall 3 are aplurality pf perforations 12 which constitute air inets.

Along its upper side the burner pi e 10 is perforated at regularintervals with a row of jet openings 13, over which positioned in directvertical alinement is a row of vent openings 14, cutting through thelining B, said openings being spaced at longer intervals and cut tolarger diameter. Altei-hating individually with the vent openings 14,and arranged in a row directly above the latter are the dischargeopenings l5, cut through the top plate 1 of the casing. Obviously, theaggregate area of either the vents or the discharge openings amounts tobut a fraction of that of the opening D.

A suitable rail 16 Ispaced a distance above the top plate l, serves as asupport for large utensils (Fig. 2) and a guard against displacement forthe smaller ones.

In use, the larger part of the heated air will be discharged through themain discharge opening D in the usual way, the balance passing throughthe comparatively small vents 14 into the chamberC,and thence, asindicated by the arrows through the secondary discharge openings 15. Byalternating the openings 15 with the vents 14, the air is deflected froma straight course and thereby retarded in its movement, thus assistingin forcing the larger volume of air through the main discharge openingD.

By having the burner jets nearer the perorations in the lining than tothe opening D, the entry of the heated air into said per-v foration isfacilitated. Y

The hollow fioor of the device serves at once as an insulating mediumwhereby the air within is protected against cooling prior `to passingthrough the opening D, and as a protection to the floor of room` againstscorchingl j j j Y I claim: t l

In a combined heater and cook stove, the combination, a rectangular'long casing having flat surroundin outer Walls and a at top and bottom,said top having a row of holes, and the front wall having a long narrowheat discharge opening for dis charging heat into the room, said openingextending to the end walls and being located as a whole, nearer thebottom than the top of said casing, a lining sheet for the casingextending longitudinally of the ca sing to the end wallsthereof, andtransversely of thecasing in a curve from the 'upper edge of saidopening upwardly to a point adjacent the top,and downward intocontacting relation with a vertically point on the rear wall and thenadjacent to central i a point longitudinally central of the bottom andterminating at the lower edge of said opening, whereby is formed ankupper and lower air chamber located respectively directly under the top,and immediately above the bottom of the casing, the transverse sectionof said air chambers being approximately symmetrical about a verticallongitudinal plane central of the casing, whereby the heated air will-beevenly distributed on either side ofsaid planein said "chainbers, a rowof perforations in the top of said lining arranged longitudinallycentral of the casing, and being appreciably smaller than said holes inthe top of the casing, a gas burner havingfa rowy ofgas outlets ex:tending longitudinally centrallyl of. the `casing and locatednearerfsaid perforation's than to the upper edge. olt said heatdischarge opening, so as to Jform an `upper relatively deep area betweensaid burner and said opening, whereby to facilitate the entry of therising heated air Jfrom said jets throughsaid perforations in the liningand said holes in the top of the casing, and airrinlets in the end Wallof said casing adj acently surrounding said burner, said air inletsbeing wholly above said heat discharge opening.
